摘要
椰心叶甲是棕榈科植物的一种危险性入侵害虫,属国家检疫林业有害生物,2005年在河口县首次发现。为了有效防治该害虫,2005～2006年在河口县观察研究了该虫的生物学特性。结果表明,该虫在河口县1 a发生6代,无明显越冬期,卵期3～10 d,幼虫期17～73 d,蛹期5～8 d,成虫产卵前期9～30 d。完成一个世代需34～121 d,夏季历期较短,冬季历期较长。通过防治试验,提出椰甲清粉剂挂包法、树干打孔注药法、喷雾防治法、生物防治法等防治措施。
Brontispa longissima is a dangerous invasive insect pest firstly found in Hekou County in 2005, which belongs to tl^e national quarantine forest pests of China. In order to control the insect pest, its bio- logical character was observed in I-Iekou County from 2005 to 2006. The insect has 6 generations a year without distinct over-winter time. The eggs stage lasts 3-10 days, the larvae stage lasts 17-73 days, the pupae stage lasts 5-8 days, and the adult stage lasts 9-30 days before laying eggs. A generation lasts 34- 121 days depends on seasons. The summer generation lasts a shorter time, and the winter generation lasts a longer time. Six control methods for the insect pest are proposed based on the field tests.
